Here is the Dojo example of what I am trying to achieve: https://dojo.telerik.com/ewAmuVok.

The fields on the grid part of gantt should remain editable, In this case title is editable and I can edit it inline. Now, the challenging part is when I double click on the timeline task template, it opens the default editable modal. If I make use of edit for gantt, it disables the inline editing of the grid part of gantt and I can override the default behavior.

I am trying to achieve both - inline editing and open custom modal popup when double clicked. 

Any inputs will be appreciated. Thanks in advance.

edit: function(e){
    e.preventDefault();
    alert("edit");
  }

Hello Vaishali,

As far as I can understand, you want to perform different actions in the edit event handler, depending on whether a cell is being edited or the pop-up is about to be opened. If that is the case, you could check the container element, which is part of the event arguments. In case its role is a window, a pop-up is about to be opened. If it is not, the in-cell editing is on its way:
edit: function(e){
  var container = e.container;
   
  if (container.attr('data-role') === 'window') {
    console.log('Pop-up is about to be opened.');
  } else {
    console.log('Cell is about to be edited');
  }
},

Here you will find a modified version of the sample sent implementing the above suggestion.

Hi,

This is correct. However, I also want to prevent the popup from opening. Is there any way to achieve it?

Thanks!

Hi Vaishali,

You can prevent the popup from opening by calling the preventDefault method:
edit: function(e){
  var container = e.container;
 
  if (container.attr('data-role') === 'window') {
    console.log('Pop-up is about to be opened.');
    e.preventDefault();
 
  } else {
    console.log('Cell is about to be edited');
  }
}

Modified dojo example.
